Affected services: (all will experience downtime of 5 minutes or so)

Public sites:
* download.mozilla.org (no database access)
* mailing lists that are gatewayed to newsgroups (news will still be
available, mail will be queued, so no messages will be lost, web
interface will be unavailable)

Additionally:
* Any site in the San Jose colo that uses LDAP authentication will have
a few minutes where any authentication attempts will result in failures.

Please let me know if you have any reason why we should not proceed with the planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window. Feel free to email infra at mozilla.com if you see issues past the planned downtime.
